Screen for separating long parts from bulk mixture of short and long parts, especially rubbish, comprises profiled conveyor belt and separator comb

摘要

The screen comprises a conveyor belt (200) with a first turning region (1100) where the bulk goods are received and a second turning region (1300) where the bulk goods are discharged. The belt has a surface profile extending in the machine direction (204) with profiles (202) and intermediate grooves (203) for receiving the small parts. A separator comb (1310) in the second turning region has prongs extending into the grooves in such a way that the small parts pass beneath the prongs and are divided towards a first flow (405), whilst the large parts on top of the profiles or in the grooves are retained by the prongs and diverted towards a second flow (406).
